This invention relates to quotation indicating boards and the likeapparatus such, for example, as brokers stock or commodity quotationboards, the invention being particu larly'applicable to automaticelectrically operated equipment of this class.

The objects of this invention include the provision of apparatus andequipment of the above-indicated class which will'be adaptable with awide degree of flexibility to various fication and. illustrate, merelyby way of eX- ample, several embodiments of'the invention.

The invention consists in such novel features, arrangements andcombinations of parts as may be shown and described in connection withthe apparatus herein disclosed by way of example only and. asillustrative of preferred arrangements.

Fig. 18 is. a View similar to that shown in; Fig. 17 showing thecontainers illustrated in Figs. 14 and 15.

Referring to Fig. 1, it will be noted that a. brokers board is providedto exhibit quotations in substantially a conventional arrangement. Theboard here shown may comprise a plurality of sections as, for example,at 20, 21:, 22 and 2.3, which are demounta'ble with respect to eachother. These sections may be arranged in a plurality of side-bysid'etiers" resting upon a suitable supporting frame, as at 24. Thesections of each tier may rest one upon another. A typical board mightbe a made up of sections each having indicators I for exhibiting thefluctuating quotations of ten stocks. Five of such sections may beconveniently arranged one on top of another'to form a tier, and then twoOfSUClLiZlGIS side by side would have a capacity for quotingonev hundredstocks or other items.

Along the top edge of each section, space may be provided, as at 25, forpainting or otherwise applying the conventional abbreviations indicatingwhich stock or other item is being quoted by the indicators immediatelybelow in the same section. At the left-hand side of the board a suitablesection of sheet material, as at 26, may be secured upon which may bepainted or otherwise indicated the conventional indicia such as toindicate the ()pen, High, Low and Last quotations of any particular itemas well as corresponding indicia denoting yesterdays High, Low andClosing quotations. Since the numbers exhibiting the previous daysquotations are ordinarily changed but once each day, such numbers mayconveniently be of the ordinary manually changeable type comprisinginterchangeable slips of cardboard or other material bearing numbers,such slips being retained upon the board in a conventional manner inslots as, for eXampie,

indicated at 27 in Fig. 2.

On the other hand, for the fluctuating quotations automatic changeableindicating units may be provided as shown in Figs. 3, 4 and 6, and thesame will be hereinafter described in detail. Where the board is to beused for New York Stock Market quotations, each quotation, such forexample as the opening quotation of a particular'stock, ordinarily mayrequire the use of four digit indicators, respectively, for thehundreds, tens, units and fraction values, and therefore where fourquotations, namely, Open, High, Low and Last, are'to be simultaneouslyexhibited, a total of sixteen digit indicating units must be provided.According to the arrangement shown in Fig. 3, such digit indicatingunits may be conveniently arranged in groups of four, each groupcomprising the units necessary for one quotation of one stock, and inthe embodiment here shown, each of such groups of four is arranged to bequickly demounted in respect to the larger demountable sections.Furthermore, as will be here'- lnafter further explained, individualindicator units of each of such groups of four may also be readilydemounted. The demountable features of the sections, groups of units,and units include not only the features of the mechanical supportingstructure but the electrical connections, in each instance may, ifdesired, be simultaneously demounted substantially without interferencewith the electrical connections to adjacent sections or units, as thecase may be.

Such demountability in respect to themechanical and electrical featuresnot only makes it possible to quickly inspect, repair or replace anysection or unit, but such fea- Lures are of particular advantage inconnec-- tion with an automatic electrically operated brokers board fornumerous other reasons. If the quotations of a large number of stocksware exhibited with sixteen digit indicating units used for each stock,the necessary multitude of units may, according to this invention, bestandardized and made interchangeable. Furthermore, the sections beingseparable may be arranged to best suit the requirements of the brokerand so as to best fit into the space available at his office. Forexample, a number of tiers greater or smaller than two may be arranged,or if the brokers space is relatively narrow, a large number of sectionsmay be placed one on top of another. Also, if necessary, the sections ofone tier may be placed at an angle to those of another tier to best fitthe space available. As the number of stocks which the broker desires toquote is increased or reduced, the corresponding required number ofsections may be in-- creased or decreased without interfering with themore permanent sections, hence no wasted or unused sections or spacesare necessary on the board to 'usure the desired capacity for futurepurposes. Since the indicating units and groups thereof may, accordingto this invention, be standardized and may be quickly interchanged evenby an inexperienced person, only a small number of spares need beprovided for replacements or additions in emergencies.

With the form of demoun'mble construction hereinafter described, theelectrical connections to the board may be made flexible and quicklydetachable, and-this, together with the demountable form of units, makesit possiblefor the broker to exhibit the stocks of connection wires toother sections and units. llso, since the units are interchangeable,those which exhibit the morerapidly fluctuating stocks, if desired, maybe occasionally interchanged with indicating units of inactive stocks,whereby there willbe less tendency for particular units to become wornout before others.

The quotation board here described may have its quotation indicatingunits interchangeably connected to selecting apparatus, as for examplein the manner disclosed in the cop nding United States patentapplication of Robert L. Daine, filed September 17, 1927, Serial No.220,244. entitled Methods and apparatus for indicating quotations orother items. Patent No. 1,658,516 of February 7 1928. actuating circuitswith which such a board may be operated may be of various forms. suchfor example as that described and claimed in the copending applicationof The selecting apparatus and the core of the magnet 31. drums 29 maybesecured 1n respect to a teeth of the star wheel.

FrancoisiFavarger, filed January 16, 1923, Serial No. 613,012, entitledElectricalimpulse transmitting devices, and the pending patentapplication in Switzerland of F abrique *D Appareils 'Electriques Favarger A., of N euenburg, Switzerland, No. 47,911, filed April 5, 1927upon which the copending United States application of Frischknecht et'alSerial No. 267,680, filed April 5, 1928, is based.

Referring to Figs. 3, 4 and 6,the details of construction of theindicator units here shown will now be further/described.

The digits to be exhibited may be ary ranged as at 28, around theperiphery of r tatable drum members as 29, which may be enclosedwithinframe members as at 30. Within each of the frame members an operatingmagnet as at 31 may be mounted to cooperate with an armature member 32,pivotally mounted as at 33; a leaf spring 34 en gaging a suitable stopmember as at 35 may be secured to the armature 32-t0 normally retain thesame in a position spaced from Each of the star Wheel as at 36, which inturn is designed'to engage an operatingfork or'pawl member 37, securedto'and operated-by'the armature32. The star wheel 36 and operating fork37 are preferably ofthe particular shapes and relative dimensionssubstan tially'as shown-in Fig. '4, and the same are designed tocooperate in a manner such that with each .movement of the armature andthe fork member 37, the star wheel;36 together with the drum member 29is advanced always in the same direction through an angle subtended bythe space between two The star wheel preferablyhas a number of teethequal to the number of digits or digit spaces to be exhibited at theperiphery of the drum and in the example shown eleven teeth are used,

providing for ten digits and a blank space. Accordingly, whenever anelectrical impulse is transmitted through the magnet the drum isadvanced through such-an angleas to re-' move fromexhibition onedigit,and to ex- ;jjhibit the next succeeding digit or space.

For normal operation of the unit, current ma be su lied to one windin ofthe magnet througha pair of terminals, as. for ex: ample, at 38 and 39.However, when a quoation is to be changed, it may be found to beexpedient to first restore the indicating unitor a group of such unitsto a zero position or position of rest. For this operation a separatecircuit including a second winding may be applied to the magnet 31,

which circuit ,may either be brought in through two independentterminals, or as in the form illustrated 1nthe drawlngs, one

additional terminal '40 may.be-used,;in conjunction with one ofthe-terminals 38-or39 acting asa return conductor commontobothcircuits.--

The terminal 40- may be connected 5 to the winding of the magnet by wayof a circuit breaker, comprising a pair of cooperating H spring contacts41. Toactuatethe-members 41 a contact operating'member '42; may bepivotedto the frame as at 43' and formed with an extension 44 forengaging anin-su' lating stud 45 which acts to separate the I contactsat 41 whenever the member- 42 engages the'same. The member'42 may alsobe provided with a cam portion46, normally resting against a stop pin 47affixed to the main in closed circuit position."

With. the above described constructional series of impulses may be sentthroughthe circuit of terminals 38-and39 to rotate'the drum to exhibitthe desired digit. Therea'fter, when-it is desired to-change 'theexhibita series of, say, 11 impulses may be appli e' to the circuit of terminal'40 and'such im-'* pulses will be effective in operating themag net andturning'thedrum-with a'step' by-ste'p movement until the drum arrives atthe'zero position, whereupon the contacts 41 will separated and thecircuit broken through the:

magnet 31 rendering'the circuit of terminal 40'inelfect1ve tofurtheractuate the'drum unt l after the samehas'been resetas 'deslred' byimpulses through the circuit-of terminals 38 and 39. The details ofthisindicator and the electrical circuits for controlling the same, exceptfor the features "hereinafter" claimed, form no part of the presentinvention but are described andclaimed inthe copendin g plication ofFrischknecht et' a1. Serial 258,219,fi1e d1\4arch1,1928.

As shown inFig. 3, the frame portio ns,- or

The .group'of 4indicating units when thus assembled :will: be readlly handled as asingle quotati'onunit;

In order that such unit may be quickly insert-- ed or removed fromasection of the board without particular --attention being paidtothe'contacts, a quick-detachable contact are,

group of indicating units. Within such strip a plurality of cooperatingpairs of contact terminals as at 52 may be mounted, a number; of suchterminals being provided equal to. the number of terminals on theindicator units. Each of the indicating units may be provided with aninsulation contact supportingportion 53 upon which the terminals as at38, 39 and 40cmay be mounted so as to be slidably embraced by thecooperating spring terminals 52 when the group of indicating units isslid into place. In this manner dependable, quick-detachable connectionsare provided for all of the terminals for each group of units.

Referring more particularly to Fig. 2, it will benoted that from eachpair of terminails-52, connection wires as at 54 may be provided, vto aquick-detachable plug member 55,

; which is shown and described in full detail in the above mentionedpatent toRobert L.

Daine. From the detachable plug members 55 flexible cables or lead wires56 may extend. to the selecting or other apparatus as above referredlto.

Referring to Fig. 7 a board section 57 is here shown comprising an outerframe formed of suitable angle irons and of such shape that several ofsuch frames may be readily placedeither side by side or one on to'pofanother. The section may be subdivided vertically into compartments onefor each stock, by vertical partitions as at 58; each of such partitionsmay be formed with 3 struck-out lugs as at 59, such lugs forming asshown, meansfor slidably engaging the lIldicating unit, supportingplates 50, and also forming supporting means for the contact supportingstrips 51. The general arrange- '5 ment of the indicator units mountedin operating position is shown in the drawings as isalso'the detachableplug member 55 and the quick-detachable contacts at 52.

V Spaces for receiving slips indlcating the previous days quotations maybe provided at indicated at 60. The front of the section may be providedwith a suitable facing panel 61 having openings opposite each of theindi- In Figs.i9, 10 and 11 a modified construccomprising-section framesas at 62 having vertical supporting strips 63. In this in- V stanceangle 1rons as at 64 may be welded or otherwise secured to the strips 63for slidably receiving the indicator mounting plates 50 aswell as theinsulation contact supporting strips 51'. \Vith the sectional indicatorboard'provid- :d by this invention, the proprietors of brokerage housesmay also provide an additional service to such of their customers ashave private offices. That is, each of such customers who may beinterested principally in a relabively small number of stocksmay havetheir connections need be changed.-

private offices equipped with one or more indicator'board sectionscontrolled from the same source as the main brokers board of theestablishment. Indicators of these additional board sections arepreferably made interchangeable in accordance with the inven tion of theabove mentioned patent to Robert L. Daine. In this manner the specialcustom ers may be provided with an indicator board of almost universalflexibility as to service provided, yet such board may be of relativelysmall dimensions.

Further modifications of the invention are shown in Figs. 1218 in whichcompartments are provided for digit indicators. As shown in Figs. 12 and17 four of such compartments as at 65 may be arranged in side-bysiderelationship within a single container 66 designed to be slidablyreceived between division plates as at 67, which in turn form a part ofa section frame. Electrical impulses for operating the indicators may beconducted thereto through a flexible cable as at 68 passing through therear wall of the compartments 66 and substantially permanently affixedin respect thereto in any suitable manner, such as indicated at 69. Thenumerous wires within the flexible cable may be either permanently ordetachably secured to their respective indicators as at 70. With thisform of construction, the front of the indicator board may be madesmooth and continuous as at 7l except for the openings- 72 forexhibiting the digits; This form of construction is particularlyadaptable to brolrers boards which are accessible from the rear,inasmuch as the digit indicators for one quotation as contained withinone of the compartments 66 may be slid out of the indicator board frametoward the rear and the electrical connections through the cable 68 neednot be disturbed. VJitlrt-his arrangement indicators may be interchangedat various parts of the brokers board to enable the broker to rearrangethe display of the stock quotations and such rearrangement may besecured either with or without interchangeability of the particularitems quoted, according to the abovementioned Daine patent. If

desired, the indicators per se may be made to be removable from thefront of'the compartments 65 after the compartments 66 have been removedfrom the brokers board, or if desired, the four separate indicators maybe substantially permanently mounted within the compartments 65, inwhich case all separable contacts at the brokers board itself maybeeliminated. With this construction a brokers board may be rearrangedand repaired from the rear without the workmans obscuring the view atthe front of the board and also, if merely rearrangement of the stockson the board is desired, no electrical In Fig. 13 the rear view of partof an as- 7 sembled bro-kers board is indicated showing the manner inwhich four of the compartments or containers 66 may be arranged, one ontop of another, to provide for the four quotations for one stock, namelythe Open, High, Low and Last" QUOttLt-IOHS. The

construction of the containers and their arrangement in the board isalso clearly shown inl ig. 17. If desired, the cables 68 as running toeach quotation may be joined to form a larger cable 73 individual to onestock or other item. 7

- Figs. l4, l5 and 18. illustrate. a modified arrangement similar tothat of Figs. 12, 13 and 17, exceptthat the indicators for one stock orother. item may be all placed within a single container as at 74 havingfour smaller subcompartments, 7 o. The subcompartments in turn are eachdesigned to contain the four digit indicators necessary for. onequotation. In this instance, a single cable 76 providing for electricalcircuits of all of the indicators for one stock may be substantiallypermanently aiiixed in the compartment 74: in the manner shown.

Fig. L6 illustrates the front View of a brokers board as embodying themodifications of either Figs. 13 or 15. This figure also illustrates adifferent. arrangement of the board sections. Sections of. the brokersboardwhich are to be filled with the digit indicators are indicated at77. In some instances, for the sake-of economy of space, brokers mayprefer not to exhibit previous days quotations, and to provide for suchcases the board sections as at 7 8 upon the face of which yesterdaysquotations are posted, may be made separate and detachable from thesection 77, the section 78 being eliminated if the broker so chooses.

In the first modification above described, the'board sections wereprovided with spaces for the indicia. denoting the stocks quoted. Ifdesired, according to the construction shown in Fig. 16, such indiciamay be applied toboard sections as at 79 which are also constructedindependently of the sections 77 and 78; Withthe indiciathus on separatesections, changes in the markings may be much more convenientlyeffect-ed, since it will be possible. for an indicia section to beprepared with the desired characters painted or otherwise affixedthereon, and the old indiciasection may he slid out and the new in"dicia' section inserted substantially without interruptionof theoperation of the board. Furthermore this construction permits digitindicator sections to be usedinterchangeably ith various indiciasections so thatample provision may be made for all contingencies andthe brokers desires, as to the indicia, without: making it necessary tomaintain on hand an extra quantity of the indicator sections.- Also, insome forms of construction, it may be found advisable to utilize thespace within the sect-ions 78 and 7 9 for the operatbrohers boards toarrange in a vertical tier the va 'i-ous quotations, such as Open, High,Low and Last, for each stock. The space necessary for such quotationsfor one stock, together with the space required'for yesterdaysquotations and the control wires and devices, is such as to besubstantially equivalent to the desirable height of board section.Therefore, with the preferred embodiments of the invention as heredisclosed, each section comprises the indicators for the quotations of asingle horizontal row ofdifferent stocks. Inasmuch as the spacenecessary for each stock is considerably greater in its verticaldimension than in the horizontal direction, and while'on the other handthe space available in brokers ofiices is generally greater in itshorizontal dimension than in its vertical dimension, for this additionalreason we find it preferable to limit the height of the sections tothat-necessary for the quotations for one stock-rather than providingfor a plurality of stocks one above another in each section.Substantially, the widest possible range of flexibility of arrangementof the brokers board to fit thespaces generally available, therefore, isassuredby the constructions shown.

The usual practice as followed in the design of sheet metal frame workand the like constructions may be here followed as toconstructionald-etails which are not specifically referred to herein.

l Vhile the invention has been described in detail with respect toparticular preferred examples thereof which give satisfactory results,it will be understood by those skilled in the art after understandingthe invention, that various changes and modifications may be madewithout departing from the spirit and scope of the invention and it isintended therefore in the appended claims to cover all such changes andmodifications:
